生物钟将环境信号与内部信号结合起来，协调各种生理输出，使它们在一天中最合适的季节或时间发生。最近在拟南芥中使用系统方法的研究扩大了我们对中央昼夜节律振荡器的分子调控及其与输入和输出途径的联系的理解。类似的方法也开始揭示生物钟对作物物种关键农业性状的重要性。在这篇综述中，我们讨论了该领域的最新进展，包括：对植物时钟分子结构的新认识；时钟组件与输入和输出路径之间的机械联系；我们对生物钟基因对农学重要性状的重要性的认识也在不断加深。
Circadian clocks integrate environmental signals with internal cues to coordinate diverse physiological outputs so that they occur at the most appropriate season or time of day. Recent studies using systems approaches, primarily in Arabidopsis, have expanded our understanding of the molecular regulation of the central circadian oscillator and its connections to input and output pathways. Similar approaches have also begun to reveal the importance of the clock for key agricultural traits in crop species. In this review, we discuss recent developments in the field, including: a new understanding of the molecular architecture underlying the plant clock; mechanistic links between clock components and input and output pathways; and our growing understanding of the importance of clock genes for agronomically important traits.
